CRACK AND sac,V Pnoor CORNER-STRIP. v

To all whom it may concern.' l

Be it known that I, GUs'rAv N. HAILGREN, a citizen of the United States, and a resident of Bayonne, in the county of Hudson and )State of New Jersey, have invented certain new and useful Improvements in Crack and Sag Proof Corner-Strips, of which the following is a specification. n

This invention relates to crack and sag proofcorner-strips. Its object is the production of strips which when secured to the juncture of a pair of walls making angles with each other, will prevent cracks at said juncture in case any sagging takes place of the walls. By this means wall paper or decorations on the wall adjacent to their juncture are preserved. The strips are p longitudinally and slidablyV connected at their juncture, and thereby permit the walls to sag,VY without injuring the appearance of the wall paper orthe decorations that may be thereon. v y Y In the accompanying drawing Figure 1 represents an elevation of a pair of strips exemplifying the invention with the lath of one of the Walls lwith which it coacts; Fig. 2 is a top plan view of the strip shown in Fig. 2, with its coacting walls; Fig. 3 is a front elevation of one of the details of the in vention; Fig. 4 shows a top plan view 0f F1g..3 and Fig. 5 shows a top plan viewk of a pan' of the strips on a reduced scale secured to a pair' of walls. i

A strip 20 preferably of Wood is shown with the front face 21, the Vrear face 22, the beveled endv 24 and the tenonV 25. An accompanying strip 28, also preferably' of wood is indicated with the front face 29,

rear face 30, beveled end 31 and the inortise 32, which latter engages the tenon 25, to provide a longitudinal slidable joint between the strip On the front faces 21 and 29 of the stri s there is secured the wall paper 36 in t e usual way, and at the jointure B8 of the strips, the paper is cut. VTo the rear faces 22 and 30 of the strips is secured, by means of tacks 41, a piece of fabric 42, which is preferably dust and water proof and protects the joint between the strlps. Clamps preferably of metal join the strips on their rearrfaces at intervals. Each of the clamps comprises the body portion'44, with the legs 45 and 46 at right angles thereto. A tapered hook end 47 is formed with the leg 45, and a taperedy hook end 48 is formed Specication of VLettera Patent. Y Application filed July y15, 1918. Serial No. 244,922.

with the leg 46. The hook end 47 is made to enter the beveled end 24 of the strip 20, and thehook end 48V is made to enter the rear assing through the fabric 42. p 5

A' framing 50 of a wall has connected thereto the studs 51 and 52 and a second wall at right angles to the first one, is indicated at 53 with the studs 54 and 55. Lath n 58 are nailed in the usualway to the studs 51 and 52 and lath 59 are nailed to the studs 54 and 55. Plaster 60 and'61 covers the' lath in the usual manner and engages the beveled ends 24 and lirespectively of the strips 20 and 28, thereby enablingthe strips to have their outer surfacesin line with the outer surfaces of the plaster.

In case the walls sag, each of thestrips will move with its wall and the jointure bepaper 36 will not show any crack. The fabric V42 will give sufficiently and the '75 tween the accompanying ends of the'wall clamps having thebody portions .44. will swing on their hook ends to permitthe strips with their walls to move longitudinallywithout spreading. In place oficoverin'g the strips and walls with wall paper, they maybe decorated. The invention provides means for preventing cracks at thejuncture of the walls, and thereby preserves the wall paper or the decorations and the like with which the walls may be decorated.

The invention may be modilied in various ways within the meaning of the claimsV and these modifications are intended to be included in the spirit of the claims.

Having described my invention what I desire to secure by Letters Patent and claim isz- 1. For the juncture Yof a pair of walls with plaster the combination of a pair of strips slidably connected at a pair of accompanying edges thereof, one of thek strips fastened to one of said walls and its plaster, the outer face ofthe strip in line with the outer face of the plaster, the other strip fastened to the other wall and its plaster, and means to prevent the strips spreading and at the same time allowing them to slide one relatively to the other. Y

2. For the corner of a pair of walls the combination of a pair of strips and plaster, the strips slidably connected at a pair of their accompanying edges, one of said strips fastened to one of said walls and plaster and the other strip fastened to the other Wall andwits plaster, and a clampV connecting said strips, permitting one. strip to slide with respect to the other, maintaining them in operative position and preventing them spreading.

3. F or the juncture of a Ypair of Walls with.

plaster the combination of a pair of. strips, one of said strips fastened to one of said Walls and plaster, the other. strip fastened to the other Wall and plaster, one ofsaid stripsV having a mortise formed therewith and the other strip having a tenen engaging said mortise, and clamps each with a pair of ing hook ends, the said hookends engaging said strips and shaped to enable one strip to` slide with respect to the other and maintainthe mortise joint ofthe stripsinoperative. position.

4. The` combination of a' pair of walls making angles with each other, plastercovering each Wall,va pair of strips fastenedA to the Walls atth'eir juncture and embedded'inthe plaster, the strips making angleswith yeach other` and slidably connected at their juncture, means to maintainthe strips in shdable operative posltion and a fabric vcovering the rear faces of the strips yto maintain their juncture dust proof, the said fabric covering said juncture in all positions of the strips.

5. The combination of al pair! of Wallsv making angles with each other, plaster covering a face of each Wall, a pair o strips making angles with eachother and located in thecorner of the Walls, e-ach of said strips having a beveled side land the other sides ofthe strips longitudinally and slidablyl locking with eachother, A'one of said strips fastened to one Wall and engaged bythe plaster thereof and theother strip fastened to the other Wall and engaged by the plas.- ter of the latter, means to render dust .proof the juncture of the Walls indifferent Aposit-ionsofthe latter, Wall paper covering one Wall and Wall paper covering the other Wall, lthe said Wall paper meeting at the juncture of the strips so that one Wall paper can move with its strip andk Wall independently ofthe other,'a` clamp' With a pair of hook 'ends engaging said strips the* hook endsshaped vto permit the strips to longi-y tudinally vn iove with respect to eachother.
